NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented May 20, 1913.

Application filed July 17, 1912. Serial No. 709,901.

To all whom it may concern:

Be it known that we, J OSEPH Q. TAYLOR and CHARLES T. EATON, citizens of the United States, and residents, respectively, of Taunton, in the county of Bristol and State of Massachusetts, and Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Non- Refillable Bottle, of which the following is a full, clear, and exact description.

Our invention relates to storage vessels provided with means for preventing the refilling of the same; and it comprises certain improved features whereby the inflow of liquid after the vessel has been emptied is effectually prevented.

The improved features in question include a member acting as a valve to check the inflow of liquid, this member being buoyant so that it will be carried against the edge of the opening through which the liquid must pass to enter the interior of the said vessel and efiectually close this opening.

Reference is to be had to the accompanying drawings forming a part of this specification, in which the same characters of reference indicate the same parts in all the views.

Figure 1 is a vertical section showing the parts in position to prevent the refilling of the vessel; Fig. 2 is a similar view, showing the manner in which the same can be emptied; Fig. 3 is a horizontal section on the line 33 of Fig. 1; and Fig. 4c is a vertical section of a modification.

Referring particularly to the drawings, we show our storage vessel as comprising'a body 1 having a hollow. projecting boss 2 which is internally screw-threaded, as shown at 3, and into this boss is screwed the neck 4, which has a shoulder 5 fitting against the outer end of the boss, and an externally screw-threaded projection 6 which enters this boss 2 and engages with the screwthreads on the inside of the same to cause the body and the neck to be secured together.

The body is provided at the base of the boss 2 with an internal annular flange 7, centrally perforated to provide an outlet opening 8, and on the outer surface of this flange 7 is placed a circular washer 9, which is engaged by the inner end of the screw-threaded boss 6, to act as a packing and form a tight joint to prevent any leakage of the contents of the body between the screw-threads on the boss and the neck and the shoulder 6 carried by the neck and the end of the boss 2.

The outer end of the neck is provided with a recess shown at 10, and a pouring lip shown at 11. Below the recess 10 the neck 4 is substantially solid, but is provided with passages leading to a counterbore 12 at the inner end of the neck, this counterbore opening through the end of the projection 6, as shown particularly in- Figs. 1 and 2. These passages are shown at 13 and 14:, the former being for the flow of air and the latter for the flow of the contents of the vessel. They are preferably arranged at diametrically 0pposite points so as to open into the bore 12 from opposite sides. The solid portion of the neck 4 is further provided with a cylindrical bore 15 arranged centrally of the same, communicating at one end with the counterbore 12 and with the bore 14 at its inner end through a port 16. The bore 15 receives a ball 17 of porcelain or metal, or any substance which is heavier than the liquid which is intended to be stored in the Vessel 1, and which will not be corroded by contact with the said liquid; andanother ball is shown at 18, which is of larger diameter than the ball 17, and is of such specific gravity as to float upon the liquid that is stored in the vessel 1, this ball 18 being too large to enter the bore 15, as shown. The ball 17 is of somewhat less diameter than the bore 15, so that it can move into the same, while the ball 18 is of larger diameter than the bore 15, so as to be obstructed by the inner end of the counterbore 12 after moving away from the edge of the opening 8 and the corresponding opening through the ring 9. This latter ball 18 fits against the edge of the opening through the packing ring 9 and prevents the inflow of liquid theret-hrough.

The storage-vessel 1 is filled with the liquid contents intended for the same before the neck & is fitted thereon. After filling, the ball 17 is placed in the bore 15 and the buoyant ball 18 is fitted into the bore 12. The packing ring 9 is then placed upon the end of the boss 2, cementing the same thereon, if desired, to hold the balls in place, and the neck 4 is then screwed home, a suitable cementing substance being applied to the screw-threads at the end of the boss 2 and the shoulder 6 to make sure that the neck will be inseparably secured to the body of the vessel 1 after the same has been screwed up as far as the threads will permit. This cement will hold the neck to the vessel and prevent the detachment of the neck without breaking it.

The contents of the vessel can be discharged at will by inverting it as shown in Fig. 2. The ball 17 will drop into the inner end of the bore 15 and the ball 18 into the end of the bore 12. The liquid will now flow out through the aperture 8 and through the packing ring 9 and passage 14L past the pouring lip 11, air passing through the opening 13 to fill the storage vessel as the liquid fiows out of the same. hen-the vessel is caused to resume its normal position the ball 18 will close the opening 8, as shown in Fig. 1, and the comparatively heavy ball 17 resting thereon will hold it so tight against the edge of the opening through the washer 9 as to seal the storage vessel 1 against the entrance of any liquid with which one might attempt to refill the vessel. It the vessel is laid horizontal, so that the weight of the ball 17 will not be effective to hold the ball 18 to its seat, the buoyant qualities of this ball 18 now come into play, and any liquid which might pass into the counter-bore 12 will fioat the ball 18 and carry it against the edge of the opening through the packing member 9. This ball will now act like a one-way valve and effectually obstruct the flow of liquid, so that the body 1 cannot be refilled.

In the modification shown in Fig. i a vessel 1 is shown as having a neck 19 having a v bore or passage 20, and connected to the body of the vessel 1 by means of a contraction 21 which serves as an inclined shoulder to receive a plate 22 having a central opening through which the liquid contents of the storage vessel 1 passes. This plate 22 is held in place by a member 23 which is made detachable from the neck and is inserted in the bore 20 and cemented in place to hold the plate 22 in position. This plug 23 has grooves 24: and 25, corresponding to the grooves 13 and 14 in the first form, and a central passage 26 communicating with the passage 25 through a short passage 27. 28 is the buoyant valve and 29 the heavy one, the latter being located in the passage 26. The filling plug 23 is held in place by means of another plug 80 having grooves 81 and 32 which register with the grooves 24 and 2-5, respectively, and is secured to the top of the plug 23 by means of cement 33. The operation of this form is the same as the operation of the first form.

From the. above description it will be seen that our invention is of the true non-refillable type, and that once emptied the contents cannot be replaced, no matter whether the vessel is placed in upright position or in horizontal or inverted position, and this is owing to the buoyant qualities of the member 18, which will automatically close the opening through the packing member 9 as soon as any liquid enters the counterbore 12 and starts to flow into the vessel.

e wish to have it understood that the above description is illustrative only and discloses but one embodiment of our invention, and we reserve to ourselves the right to vary the details thereof in any manner that is consistent with the scope and spirit of our invention as set forth in the accompanying claim.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

In an. improvement of the kind described, the combination of a neck having a contracted portion, a perforated member engaging the inner surface of said contracted portion, a plug having a central bore containing one-way movable valve means resting upon said perforated member, and said plug also having longitudinal grooves on its exterior surface communicating with said bore at its end adjacent the perforated member, and having a port establishing communication with the inner end of said bore and one of said passages, and a second plug secured to the outer end of the first plug and. having passages forming continuations of the longitudinal passages of the first plug.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
